6-Pack 8000mAh Replacement for Dewalt 20V Max Battery High Capacity Battery Compatible with Dewalt DCB200 DCB201 DCB203 DCB205 DCB206 Works with 20V Power Tools & Chargers

What It Is

This is a 6-pack of 8,000mAh aftermarket replacement batteries for Dewalt 20V Max cordless lawn mowers, trimmers, blowers, and other 20V tools. Each battery delivers higher capacity than standard Dewalt packs, extending runtime for larger yards or heavy-duty use.

Fitment & Compatibility

• Tool voltage: These are 20V Max (18V nominal) – they work with all Dewalt 20V Max tools and chargers, but not with 18V NiCad or FlexVolt tools.
• Compatible models: DCB200, DCB201, DCB203, DCB205, DCB206, and most Dewalt 20V Max slide-pack tools. Check your tool’s model number for “20V Max” on the label.
• Lawn mower fit: Fits Dewalt 20V push mowers (e.g., DCMW220, DCMW225) but may not fit under the mower deck cover if the battery is taller than OEM. Measure your battery slot height (roughly 4.5” x 3” x 2.5” for OEM) – this aftermarket pack is slightly larger.
• Chargers: Compatible with all Dewalt 20V Max chargers (DCB101, DCB102, DCB107, etc.). Charging time may be longer due to higher capacity.

Key Things to Know

• Capacity: 8,000mAh per battery (vs. ~1.5–5Ah for OEM) – expect 1.5–3x longer runtime, but weight is noticeably higher.
• Quality risk: Aftermarket cells may degrade faster or fail earlier than genuine Dewalt. Check warranty (typically 1–2 years vs. Dewalt’s 3-year).
• Installation: No tools needed – slide on/off like OEM. Ensure latch clicks firmly; loose fit can cause power loss.
• Common gotcha: Some users report these do not fit in tight battery compartments (e.g., certain trimmers or blowers). Test one before opening all six.

Should You Buy It

Buy this if you have multiple Dewalt 20V Max tools, need extended runtime for large lawns or heavy trimming, and are comfortable with aftermarket risk. Skip it if you value long-term durability, need a guaranteed fit under a mower deck, or prefer OEM reliability for commercial use.
